BACKGROUND INFORMATION
P. E. Stamp and Signature.
Proper format including Table of Contents, Executive Summary,
Conclusions, and Appendices.
EXISTING CONDITIONS
Description of proposed land use action.
Figure - Proposed Site Plan.
Figure - Site Vicinity Map showing the minimum study area boundary.
Description of existing site conditions and adjacent land uses.
Description of existing transportation facilities including roadway, transit,
bicycle, andpedestrian facilities.
Figure - Existing Lane Configurations and Traffic Control Devices.
Figure - Existing traffic-volumes (prefer measured within previous 12 months).
Existing conditions analysis of the study area intersections.
Roadway and intersection crash history analysis.
BACKGROUND CONDITIONS
Approved planned developments and funded transportation improvements.
Documentation of traffic growth assumptions and added traffic from other
planned developments.
Figure – Background traffic volumes at study area intersections.
Background conditions analysis of the study area intersections.
FULL BUILDOUT CONDITIONS
Description of proposed land use action and intended use.
Trip Generation - Based on most recent edition of ITE Trip Generation or
approved other rates; include daily, AM, and PMpeak hour (other time periods where applicable); provide complete documentation of calculations.
Trip Distribution - Based on analysis of local traffic patterns from collected
data or supplied by staff.
Figure – Estimated Trip Distribution Pattern (showing assignment onto major
arterial/collector system).
Figure – Site-Generated Traffic Volumes at study area intersections.
Figure – Full Buildout Traffic Volumes at study area intersections.
Full Buildout conditions analysis of the study area intersections.
Identify study area intersection and access driveway deficiencies.
WARRANTS/SAFETY ANALYSIS
Verify compliance to Access Spacing Standard or justify any variance needed.
Address potential safety problems resulting from conflicting turn movements
with other driveways and internal traffic circulation.
Determine need for storage lanes, right-turn lanes, and left-turn lanes.
Address availability of adequate sight distance at frontage road access points, for
both existing and ultimate road configuration.
Evaluate need for deceleration lanes, and channelization when determined
necessary by acceptedstandards and practices.
Evaluate whether traffic signals are warranted at study area intersections.
IMPROVEMENT RECOMMENDATIONS
Identify alternate methods of mitigating identified deficiencies.
If a signal is warranted, recommend type of signal control and phasing.
If turn lanes required, recommend amount of storage.
Identify parking/parking facility needs.
Identify pedestrian and bicycle transportation needs.
OTHER
Technical Appendix-sufficient material to convey complete
understanding to staff of technicaladequacy.
Two (2) copies of the TIA has been provided to the City for review.
